LOCOMOTIVE ASH-PAN.

Serial No. 383,972.

To all whom it may concern Be it known that we, WILnIAM R. Mo- KEEN, Jr., and JAMES H. Guovn, residing at Omaha, in the county of Douglas andState of Nebraska, have invented certain new and useful Improvements inLocomotive Ash- Pans, of which the following is a full, clear, and exactdescription, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to ash-pans and, with regard to the more specificfeatures thereof, to ash-pans of railway locomotives.

One of the objects thereof is to provide an efiicient and practicalash-pan in which the chance of dropping hot coals is eliminated.

Another object is to provide a durable and inexpensive ash-pan in whichwarpingv or burning out is done away with.

Another object is to provide a construction of the above nature in whichfull and free draft is provided without chance of blowing live coals orcinders through the air inlet openings.

Other objects will be in part obvious and in part'pointed outhereinafter.

This invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter set forth, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possibleembodielevation thereof, certain parts away in order to show theconstruction more clearly; and Fig. 2 is an end view also partially insection.

Similar reference characters refer to similar parts throughout bothviews of the drawings.

As tending to cast light upon certain features of this invention, it mayhere be noted that there is a tendency in ash-pans, and particularlythose of the locomotive type, to warp or burn out by reason of the hotcoals and cinders falling therein, which often work up a considerablefire in this part of the locomotive. This is particularly the case whenair is admitted to the lower portion of the ash-pan on account of thestrong draft due to high winds or the motionof the loco-- motive. Anywarping or other deformation tends to permit the dropping of live coals,

with a tendency to set fire to wooden trestles or bridges, and suchfires often occur with an ash-pan of the widely used types, even withthe pan in good condition, by reason of the blowing of hot coals orcinders through the air-inlet openings. The above and other defects areeliminated in constructions of the nature of that hereinafter described.

Patented Apr. 15,1913.

Referring now to Fig. 1 of the accompanying drawings, there is shown anashpan the upper portion 1 of which is formed upon a framing formed ofthe angle irons 2, upon which the mud-ring of the boiler rests, andlower angle irons 3, the body of the pan being constituted of boilersteel and the parts riveted together as indicated in the drawings. Aboutthe sides and end of this portion of the ash-pan are formed air inletports 4, the outer ends of which are guarded by upwardly flared shields5, preferably likewise formed of sheet metal. The lower portion of theash-pan comprises the sections 6 and 7, spaced, as indicated in thedrawings, in the well-known manner in order to accommodate the driveraxle. The forward portion comprises the upper angle iron 8, to which aresecured depending angle irons 9 and 10 of the curved conformationindicated in Fig. 2 of the drawings. The section 7 is, in general,similar to section 6 having the upper angle irons l1 and the curvedangle irons 12 and 13 depending therefrom, and the body of both of thesesections is formed of boiler iron as in the case of the upper portion ofthe pan, being riveted to the angle iron frame-work and thus given ageneral semi-cylindrical form which possesses a high degree ofmechanical strength and is substantially proof against warping in use.Sections 6 and 7 are provided with the ashdoors 14 and 15 having liningplates 23, each of which is hinged as at 16 and is normally secured intightly closed condition as by the pin 17 and key 18'. These sectionsare thus, in normal use, substantially imperforate although means may beprovided, if desired, as at 19, for an ash-pan blower should the same beused. Angle irons 8 and 11 are tightly held against the bottom angleirons 3 of the upper pins 20, provided with split keys 21, thus insuringa tight and secure joint and yet permitting the removal of the lowersections if desired. 4

The method of use of the above-described embodiment of this invention issubstantially as follows: Upon cinders or hot coals falling into theash-pan they drop into the lower portion thereof, which is sealed andforms thus a dead air space in which all fire is quickly extinguished.Any heat, moreover, which may be generated in this ortion of the pan canwork no harmful e ect inasmuch as no appreciable warping of the curvedsheets can occur and the doors are thoroughly protected by the liners asabove set forth. No openings nor crevices obtain, moreover, throughwhich heated particles can be dropped or blown, as is the case in formerash-pan constructions in which it has been unsuccessfully attempted toprotect the openings by screens and the like. The draft is supplied tothe grate through the air ports 4 and, by reason of the conformation ofthe shields 5, is forced inwardly in a'downward direction wardly to thefire-box. In this manner, even though a considerable degree of airpressure arises in the ash-pan, no particles can be blown through theairinlets as the incoming air rushes in a downward direction, tending toforce all solid matter to the lower portion of the pan.

It will thus be seen that there is provided a construction in which theseveral objects essentially practical nature.

'so formed and disposed as above construction claim as new and of thisinvention are achieved, and that the same is cheap, strong and durableand of an The parts are apart and are not only eflioiently to performtheir functions in the matter of retaining and extinguishing live coalsand providing abundant draft to the grate, but as a whole to possess ahigh degree of mechanical strength and be capable of a long life in use.

As many changes could be made in the and many apparently widelydifferent embodiments of this invention could be made without departingfrom the scope thereof, it is intended that all matter contained in theabove description or shown in the accompanying drawings shall beinterpreted as illustrative and not in a limiting,sense.

The essential features and combination of the invention will beparticularly set quickly assembled or taken forth in the claims, andthese are not to be limited to the particular structure illustrated, butare intended to include generically such modifications and substitutionsof equivalents as reasonably fall within the scope of the invention.

Having described our invention, what we desire to secure by LettersPatent is v 1. In an ash-pan the combination of an and thence passes upupper portion formed of sheet metal and provided with angle bars at itsupper and lower edges; a lower portion formed of sheet metal andprovided with angle bars at its upper edges; and means adapted to securethe upper angle bars of said lower portion to the lower angle bars ofsaid upper portion and form a substantially tight joint therebetween,said lower portion being in normal operative condition substantiallyimperforate and said upper portion being provided with air inlet portsand having secured thereon sheets adapted to guide the entering air in adownward direction.

2. In an ash-pan, the combination of an upper portion open at its lowerside; a

depending lower portion closed at its bottom and sides and making aclose joint with the upper portion; separable connections between saidupper and lower portions; a door in one end of said lower portion; andinlet air ducts leadin the incoming air in a downward direction throughthe walls of said upper portion.

3. In anash-pan, the combination of an upper portion open at its lowerside; depending lower portions closed at their bottoms and sides andmaking close joints with the upper portion; separable connections between the upper and said lower portions; doors, a door being located inone end of each of said lower portions; and inlet air ducts adapted toconduct incoming air in a downward direction through the walls of saidupper portion.

In an ash-pan, the combination of an upper portion open at its lowerside; substantially semi-cylindrical lower portions making close jointswith the upper portion; separable connections between said upper andlower portions; doors, a door being located in one end of each of saidlower portions; and air ducts located in said upper portion and adaptedto direct incoming air in a downward direction.

5. An ash-pan comprising an upper section provided with air inlets andadapted to directthe incoming air in a downward direction; and a lowersection adapted to receive and contain the hot ashes; and removableconnections between said sections whereby the'lower section may beremoved for repair or replacement without disturbing the upper section.

In testimony whereof we aflix our signatures, in the presence of twowitnesses.
